  2. 2. A Tomographic Measurement Technique for Irradiated Nuclear Fuel Assemblies

    Författare :Staffan Jacobsson Svärd; Anders Bäcklin; Ane Håkansson; Klaas van der Meer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; tomography; nuclear fuel; SPECT; core physics; validation; pin power; safeguards; partial-defect verification; Kärnfysik; Nuclear physics; Kärnfysik;

    Sammanfattning : The fuel assemblies used at the Swedish nuclear power plants contain typically between 100 and 300 fuel rods. An experimental technique has been demanded for determining the relative activities of specific isotopes in individual fuel rods without dismantling the assemblies. LÄS MER

  3. 3. Fast-Neutron Tomography using a Mobile Neutron Generator for Assessment of Steam-Water Distributions in Two-Phase Flows

    Författare :Peter Andersson; Staffan Jacobsson Svärd; Henrik Sjöstrand; Stephan Pomp; Ane Håkansson; Michael Österlund; Bernhard Ludewigt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Void distribution; neutron tomography; plastic scintillator; transmission measurements; neutron detection; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : This thesis describes the measurement technique of fast-neutron tomography for assessing spatial distributions of steam and water in two-phase flows. This so-called void distribution is of importance both for safe operation and for efficient use of the fuel in light water reactors, which compose the majority of the world’s commercial nuclear reactors.

  4. 4. Optimization of Equipment for Tomographic Measurements of Void Distributions using Fast Neutrons

    Författare :Peter Andersson; Staffan Jacobsson Svärd; Henrik Sjöstrand; Ane Håkansson; Michael Österlund; Stephan Pomp; Rudi Van Nieuwenhove; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : This licentiate thesis describes a novel nondestructive measuring technique for determiningspatial distributions of two-phase water flows. In Boiling Water Reactors, which compose themajority of the world's commercial nuclear reactors, this so called void distribution is of importance for safe operation. LÄS MER

  5. 5. Inter and Intra-Assemblage Characterizations of Giardia intestinalis: from clinic to genome

    Författare :Johan Ankarklev; Staffan Svärd; Johanna P. Daily; Uppsala universitet; []
    Nyckelord :Giardia; protozoa; parasite infection; diarrhea; genome sequencing; comparative genomics; genotyping; ASH; MLG; Infektionssjukdomar; Infectious Diseases; Molekylär medicin; Molecular Medicine; Mikrobiologi; Microbiology;

    Sammanfattning : The protozoan parasite Giardia intestinalis (syn. G. lamblia, G. duodenalis) is one of the most common causes of diarrheal disease throughout the world, where an estimated 500 million people are infected annually. LÄS MER
